# The graph shows the electric potential \(V\) as a function of position \(x\) along the x-axis in a region of space. Which of the following graphs best represents the x-component of the electric field \(E_x\) as a function of position \(x\) over the interval \(0 < x < x_2\)?

The graph shows the electric potential \(V\) as a function of position \(x\) along the x-axis in a region of space. Which of the following graphs best represents the x-component of the electric field \(E_x\) as a function of position \(x\) over the interval \(0 < x < x_2\)?

![A graph of electric potential V versus position x. The vertical axis is labeled V with a positive tick mark labeled V_0. The horizontal axis is labeled x with tick marks labeled x_1 and x_2. The graph consists of two linear segments: the first segment starts at (0, V_0) and slopes downwards to (x_1, 0); the second segment runs along the x-axis at V = 0 from x_1 to x_2. No other lines or text appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785830697-Q1ezrD.jpg)

- **A.** A graph where \(E_x\) has a constant negative value \(-E_0\) for \(0 < x < x_1\), and is zero for \(x_1 < x < x_2\).
- **B.** A graph where \(E_x\) has a constant positive value \(+E_0\) for \(0 < x < x_1\), and is zero for \(x_1 < x < x_2\).
- **C.** A graph where \(E_x\) decreases linearly from \(+E_0\) to zero for \(0 < x < x_1\), and is zero for \(x_1 < x < x_2\).
- **D.** A graph where \(E_x\) increases linearly from zero to \(+E_0\) for \(0 < x < x_1\), and is zero for \(x_1 < x < x_2\).
